any member of the group transmits, their radio automatically
selects a clear channel to transmit on. Other radios scanning
in the same Net-scan group will lock onto that channel
allowing all members of the group to join the conversation.
If a signal from outside your Net-Scan group appears on the
chosen channel (either with no code or the wrong code), the
group will automatically switch to a new clear channel at the
next transmission. In this way the group can continue
to communicate with minimal interference to or from
other users.
Enabling Net-Scan
Net-Scan is normally switched off by default but can be
enabled through your radio's Menu.
NOTE:

Programming channels into Net-Scan.
All radios in your Net-Scan group must have the same
channels programmed into their Net-Scan memory.
Your radio's Net-Scan memory has already been factory
programmed with 43 of the available 80 channels. The
remaining 37 channels, which consist of the 32 repeater
input/output channels, 2 telemetry channels and 3 guard-
band channels, have not been included to minimise the risk
of interference to other services on these channels.
To add or remove Net-Scan channels
With Net-Scan mode enabled, select the require channel
using the Channel Control.
